"'My'inventionfrelates ,to devices for preve'ntingthe longitudinal creepof railroad rails, such devices being commonly known as rail anchors,anticreepers, creepchecks or 5 rail stays.

[The principalobject' of the invention is to: provide a device ofthis'type, which will be simple in its construction, inexpensive, tomanufacture, light. in weight, strong and ca '10 pable of taking. affirmand reliable hold upon the rail, A further object is to pro-- vide,adevice constructed in one .pie'cef'which' may be quickly andconveniently applied to the rail-with the tools usually employed bytrack mechanics and will not be loosened or become ineffective-byvibrations, movement of the rail temporarilyin adirection the reverse.of that inwhich the rail tends to creep or anyof the other causestending to loosen the gripof rail anchors on the rails engaged thereby.V I w j My rail anchorpossesses other features of novelty and advantage,which, with the foregoing will be obviousv from the followingdescription. v

The improvedfrailanchorconsists essentially ofia bar Efthe middleportion I of which-is straightand arranged to grip the bottom of thebase flange'C; At, each side of thefportion I of the bar E .tie engaging'portionsK, and L are formed by bending the bar E downwardlyandthenupwardly. One endof the bar Eisbrought to substam retaining portion M;which, when the rail anchorfis in[ position on the rail, will extendsomewhat;.above the, bottom of the base of "the rail. The other end.ofthejbar E is made mu hz onge n ands-b n ove o f m a m.

Hjadapted to engage and] grip the upper" surface'of the ,base flange Catone side of therail. I 1

I In forming-the several portions-of the barE I pre'ferto'form onefaceo'f the portion I, gripping thebottom of theb'aseffiange C, and thefaceof'the arm'H, gripping the upper surface of'the' base fiangejQ-to beconcave as shown at E; at the same'time making: the otherface ofthebar'E fort-hose" portions convex as shown 'at'G. "If desired 7 a rolled barhaving "one" side concave and i the other convex'might'be employed.v,By'so' shapingthe' bottom gripping portion land the arm H, engagement,of each with the base fiangeC is at the edgesQ and Rfor'v the edges 0and,

jumping off the'rail if repeated blows are necessary to drive it toposition. a

The rail anchor is applied to the rail from 7 one side, the arm Hengaging the top" of the baseflange'Catjits end only andthelower cornerof the base flange C at the other side; 1 of the rail being then'engagedby the bevel end Nj, ancldriving the whole transversely upon the railuntil the retaining portion M can reaclrits final posi'tionwithjth'eface engaging the vertical edge of the baseflange (latthe sidepppositeto that engaged by the arm jThe bottom gripping portion I' and the armH- are so disposed with relation the one tothe. other fthat, as'the barE is forcibly moved @transverselyj upon the rail the edges 0 and P ofthe arm'I-I ride upon the top of the base flange C and the-edges Q andR. ofthe bottom gripping portion I ride ;upon the bottom of. the baseflange-C; and one side of'the base flange of the rail B iswedged inbetween the arm H and the portion I securely. V v I v i I y In the finalposition of the rail anchorjon the rail shown in Figures 1 and 2 thebaseflangeC is firmly gripped'b-etween the per tionIand the arm H, which,engages and grips the upper surface forv thegreater portion of thelengthof the arm H; and'is held against displacement lfrom' position, bythe engagement of thesurfaceSfof theretainin portion M with the oppositeedge of the'base flange C. 7

The direction in which the rail tends to creep is indicated'by the arrowin Figure 2. Such creeping movementis resisted and prevented by theengagement of the faces of the portions K and L with the crosstie D;which, by their form, not only provide ample surface of contact with thetie, but also provide contact with the tie D at a considerable distancebelow the bottom of the base flange C of the rail B. r

It will'readily be seen that by making the bar E relatively wide asshownin Figures 2 and 5 and by forming the faces of the base flange grippingarm H and the bottom gr ip ping portion I to present concave surfaces tothe railbase and engage the rail base along the edges Q and R of theportion 1 and O and P of the arm H there is provideda construction inwhich the pressure is exerted along the "edges 0 and P and Q, and R,tending to flatten the section of the armH and the bottom grippingportion I as indicated in the section at the plane A A in Figure 1 shownin Figure at, where the dotted lines indicated, greatly exaggerated, theshape of the section before the rail anchor has been forced intoposition and the full lines indicate the sections after being flattenedby the pressure exerted along the edges 0 and P of the arm H and Q, andR of the bottom gripping portion 1. The effect will readily beunderstood to produce a very effective and permanent grip of the arm Hupon the top of the base flange C and of the portion I 7 upon the bottomof the base flange C.

To removethe rail anchorfrom the rail, the retaining portion M is forceddownward until the lower corner of the base flange C will engage thesurface N and the whole then driven transversely of the rail in thedirectionthe reverse of that in which the rail anchor was forced ontothe rail.
